Method for the stepless regulation of the delivery of a suction valve (1) of the plate-type of construction, comprising a valve plate (3) which is actuated by an electromagnet (9) arranged in a valve catcher (6), wherein the electromagnet (9) is so controlled that, in a first control phase (11a), the valve plate (3) firmly contacts the valve catcher (6), or a damper plate (4) arranged between the valve catcher (6) and the valve plate (3) and is blocked, and that, in a second control phase (11b), the electromagnet (9) is controlled by a decaying alternating current, in order to demagnetise the valve plate (3), so that the valve plate (3) is released.

Méthode pour la régulation continue du débit d'une soupape d'aspiration (1) du type à plaque, comprenant une plaque porte-soupape (3) actionnée par un électro-aimant (9) monté dans un récepteur de soupape (6), l'électro-aimant (9) étant commandé de manière que, dans une première phase de commande (11a), la plaque porte-soupape (3) contacte fermement le récepteur de soupape (6) ou un clapet (4) monté entre le récepteur de soupape (6) et la plaque porte-soupape (3) et elle est bloquée, et que, dans une deuxième phase de commande (11b), l'électro-aimant (9) est commandé par un courant alternatif décroissant, dans le but de démagnétiser la plaque porte-soupape (3), de sorte qu'elle soit dégagée.
